Pure unarmed movement is symmetrical and rhythmic.

If you are carrying things at work, it will often make people tired, asymmetrical, rhythmic and monotonous. For example, when moving a box, the weight, volume and shape of the box stipulate that you can only move it in a certain fixed direction, posture and strength, and often you can't rest and stimulate your muscles correctly.

Therefore, when carrying at work, it is important to always pay attention to adjusting the above aspects, changing posture for a long time (if allowed), and controlling breathing rhythm, which is psychologically regarded as a pleasant exercise.
